ALBUQUERQUE, N.M. — Seven years ago today, a woman walking her dog on Albuquerque’s West Mesa stumbled across a human bone.

It was the first of many in what would become one of the largest crime scenes in American history.

By the end of the month, investigators had found the remains of 11 women and an unborn child in the dusty patch of land near 118th Street and Dennis Chavez.

It took authorities a year to identify them all.

Detectives quickly homed in on two men they thought may have been involved, Lorenzo Montoya and Joseph Blea, but there have been no arrests.

The case remains unsolved, and family members wait for answers.

In the weeks before the seven-year anniversary of the discovery burial site, the Journal reviewed scores of police reports and court documents related to the possible suspects and spoke to police about their progress in the case.
